The door is an indispensable part of the home. Some prices on the wooden doors on the market are not suitable for the owner. Therefore, more and more people choose to let the woodworker do the door. In fact, there are many problems with the door. Hua Wei Wooden Door Purple Wood Door Wooden door paint process The paint is used as a post-process for the processing of wooden door factories. Its advantages and disadvantages directly affect the final use effect. At the same time, the paint cost is also one of the largest parts of the wooden door. The types of paint are roughly divided into phenolic paint, alkyd paint, polyurethane paint, nitro paint, polyester paint, and PU paint. Among them, phenolic paints and alkyd paints are basically eliminated during the decoration due to poor texture and adhesion of paint films, and a large number of urethane paints, polyester paints, and PU paints used on high-grade furniture are used in large quantities. Nitro-lacquer is relatively simple to use and suitable for manual operation. It is used by most hand-decorated woods. However, the paint film is thin and feels bad. The effect is not ideal. Polyester paint is relatively thick, but its diluent contains helium when it is volatilized, and its hardness is slightly weaker. The most ideal is PU lacquer. PU lacquer not only has thick and thick film of polyester paint, strong adhesion and good transparency. At the same time, its good sealing performance also plays a very important role in wood moisture protection. Hardness, durability, yellowing resistance and environmental protection are also unmatched by other paints. Due to the cost (nitrogen lacquer 8-15 yuan / kg, polyester paint 18-28 yuan / kg, PU lacquer 43--65 yuan / kg), processing methods and equipment, currently on the market 90% of the use of wooden doors Polyester paint, a few manufacturers use PU paint. In general, polyester paint and PU paint have to look for color, three steps and two sides and other six processes, some brands increase the curing and waxing process. Therefore, in the selection of wooden doors, paint is one of the factors that must be considered. It directly affects the texture, feel, moisture, environmental protection, durability, resistance to yellowing and other issues. Why are wooden doors easily deformed Due to the use of wood processing, the wooden door has a large flat surface area and a small number of fixed points, so it is one of the decorative woods that are most susceptible to deformation and cracking. Because the deformed wooden door will directly lead to the sound insulation, airtightness and aesthetics of the house, understanding the cause of the deformation of the wooden door becomes a particularly important decorative knowledge before decoration. Natural wood has various factors in the growth process, resulting in uneven density of wood (sunny surface, annual density, core material and sapwood). When the wood is being planed, it changes the balance of internal stress, Deformation and cracking of wood. The high moisture content of wood is also another main reason leading to the deformation of the wooden door. With the decrease of the moisture content during use, the internal stress of the wood will gradually be revealed, eventually leading to deformation and cracking. The main method to prevent wood deformation is to use mechanical and technical methods to change the internal stress and moisture content of the wood. The most effective and common method to change the internal stress is to finger joints of pine wood or Chinese fir (smaller stress in these two kinds of wood). . The method of changing the wood moisture content is to perform secondary drying (natural drying followed by steam drying). The quality of processing in the production of wooden doors, such as the pressure, temperature, balance layer, glue and other factors of the press, will directly affect the deformation and cracking of the wooden door during use.
